Common Reasons for Replacement

• Brake pulsation from rotor wear or thickness variation
• Scoring, grooves, or surface damage on the rear rotor
• Brake noise caused by uneven rotor condition
• Reduced braking consistency during stop-and-go driving
• Service replacement for a worn OE rear rotor on Ram ProMaster vans

Installation Notes and Tips

Verify rear rotor dimensions, bolt circle diameter, and hub fitment before installation. Inspect pads, caliper hardware, and hub surfaces at the same time to help ensure even contact and proper brake operation. For best results, replace rotors in pairs on the same axle and follow the vehicle manufacturer’s brake service procedures.
